TypeScript is the new DOC format.
Create a language/format. Spend all of your effort making it ubiquitous until it becomes the default "standard" in the workplace. Then charge a metric fuck-tonne for the "official" software that makes use of it.
It's how Office became their cash cow. They create the proprietary doc format, get everyone using it, and once it's embedded in the workplace, charge exorbitantly for the software that uses it.
Once they get everyone using TS as a new industry standard, they'll find a way to make people have to pay for it. Mark my words.
I hope you're right. But my trust level for corporations is somewhere between 0 and 0.1
